A simple widget to display the newest reading from the internal temperature sensor (not available on all devices!), as well as connecting to a Tempe sensor and display it's reading at the same time!
C or F is based on the "Temperature Units" set on your watch under Settings-System-Units.
A Tempe Sensor is needed to see the Tempe data
If you like the app, and want to buy me a cold drink, you can do so by way of https://www.paypal.me/jimm58

NOTE: On watches that have Connect IQ 1.x (like the fenix3), the internal temperature will not be available, and on 2,x watches that don't have the internal sensor (like the 735), it will also be unavailable.

The internal temperature should be available right away, but with the Tempe, it can take a minute or more to connect and get a reading, so the widget will cache the last reading.  After a period of time, the Tempe data will be considered "stale" and won't be displayed. (the default is 30 minutes, but can be set to 0-240 minutes, with 0=never)

Note! on the vivoactive-hr, it can take time to hear from the tempe.  If you just tap the screen, it will extend the timeout before the widget switches back to the watch face.  On the other devices, pressing the "start" button will also extend it.

The Tempe needs to be paired as a standard sensor, and C/Fis changed based on the "Temperature Units" setting on the watch.
